Description

Die Erfindung bezeichnet ein Einsteckende für ein zumindest teilweise drehend und/oder schlagend angetriebenes Werkzeug, wie einen Bohrmeissel, Meissel oder eine Schneidbohrkrone zur Bearbeitung von Gestein, Beton oder Mauerwerk.The invention refers to a spigot for an at least partially rotating and / or impact driven tool, such as a drill bit, chisel or a cutting bit for machining rocks, concrete or masonry.

Üblicherweise weist ein drehend und/oder schlagend angetriebenes Werkzeug ein sich längs einer Achse erstreckendes Einsteckende für eine drehende und/oder schlagende Handwerkzeugmaschine auf. Zur wahlfreien Verwendung einer vielfältigen Werkzeugpalette sollte die Schnittstelle zwischen dem Einsteckende des Werkzeugs und der Werkzeugaufnahme der Handwerkzeugmaschine zumindest innerhalb bestimmter Leistungsklassen kompatibel sein. Nach der DE3429419 weist ein zur Verwendung in einem Dreibacken-Spannfutter ausgelegtes Einsteckende eines längs einer Achse drehend und/oder schlagend angetriebenen Werkzeugs, welches sich längs der Achse innerhalb eines maximalen Führungsdurchmessers erstreckt, um 120° umlaufend versetzte, an einem Axialverriegelungsende zum freien Stirnende hin axial geschlossene, Verriegelungsnuten und zum freien Stirnende hin axial offene V-förmige Führungsnuten mit einer Tangentialkraftkontaktfläche auf, wobei die Führungsnuten bei einer, dem Elffachen des Führungsdurchmessers betragenden, Länge dem Axialverriegelungsende werkzeugseitig vorgelagert sowie über eine, dem Zwölffachen des Führungsdurchmessers betragenden, Kontaktlänge schmaler als ein Viertel des Führungsdurchmessers ausgebildet sind. Derartige, auch zur Verwendung in einem üblichen Dreibacken-Spannfutter einer Schlagbohrmaschine ausgelegte, Einsteckenden sind als technische Kompromisslösung nicht Gegenstand dieser Erfindung. Die derzeit bei Bohrhammersystemen weltweit meistgenutzten, praktisch standardisierten Einsteckenden und zugeordneten Werkzeugaufnahmen beziehen sich auf die DE2551125A1 , die die Merkmale des Oberbegriffes von Anspruch 1 offenbart, und die DE3716915A1 , welche eine werkzeugseitige, zylindermantelförmige Führungsfläche, zum freien Stirnende hin axial geschlossene Verriegelungsnuten und zum freien Stirnende hin axial offene, trapezförmige Drehmitnahmenuten aufweisen, wobei zumindest ein radial versetzbarer Verriegelungskörper der zugeordneten Werkzeugaufnahme in eine Verriegelungsnut eingreifen und die axiale Beweglichkeit des Werkzeugs in der Werkzeugaufnahme begrenzen kann.Usually, a rotationally and / or impact-driven tool has an insertion end extending along an axis for a rotating and / or hammering handheld power tool. For random use of a diverse tool palette, the interface between the male end of the tool and the tool holder of the hand tool should be compatible at least within certain performance classes. After DE3429419 a plug-in end of a three-axis chuck for use in a rotationally and / or hittingly driven tool which extends along the axis within a maximum guide diameter, circumferentially offset by 120 °, axially closed at an axial locking end towards the free end, Locking grooves and the free front end axially open V-shaped guide grooves with a Tangentialkraftkontaktfläche on, wherein the guide grooves at one, the eleven times the guide diameter length, the tool before the Axialverriegelungsende upstream and over a twelve times the guide diameter amount, contact length narrower than a quarter of Guide diameter are formed. Such, designed for use in a conventional three-jaw chuck a percussion drill, insertion ends are not subject of this invention as a technical compromise solution. The currently most widely used in rotary hammer systems worldwide, practically standardized Einsteckenden and associated tool holders refer to the DE2551125A1 , which discloses the features of the preamble of claim 1, and the DE3716915A1 , which have a tool-side, cylindrical jacket-shaped guide surface, axially towards the free end end locking grooves and the free end axially open, trapezoidal rotational drive grooves, at least one radially displaceable locking body of the associated tool holder engage in a locking groove and limit the axial mobility of the tool in the tool holder can.

Die praktisch standardisierten Einsteckenden und Werkzeugaufnahmen nach der DE2551125A1 weisen einen Führungsdurchmesser von 10 mm auf, wobei je genau zwei gleichförmige, diametral gegenüberliegende Verriegelungsnuten und Drehmitnahmenuten symmetrisch umfänglich verteilt sind. An die bezüglich der Verriegelungsnuten geringfügig längeren Drehmitnahmenuten schliesst sich werkzeugseitig eine bis zum werkzeugseitigen Ende des Einsteckendes erstreckende Führungsfläche an, welche nicht zur Drehmomentübertragung beiträgt. Diese Einsteckende waren ursprünglich für einen Bohrerdurchmesser bis zu 17 mm ausgelegt und sind somit dem Bereich der kleinen, leistungsschwächeren Bohrhämmer mit einer Leistung kleiner 650 W zuzuordnen. Die zunehmend leistungsstärkeren Handwerkzeugmaschinen, insbesondere Bohrhämmer, gestatten es jedoch inzwischen, in bestimmten Betriebsmodi hohe Drehmomente auf ein Werkzeug zu übertragen. Inzwischen hat sich eine Erweiterung des praktischen Einsatzbereiches dieser Bohrhämmer bis zu einem Bohrerdurchmesser von 30 mm ergeben. Zudem werden beim Entfernen eines Werkzeugs aus dem Werkstück, insbesondere bei im Bohrloch verklemmten Werkzeugen, vom Nutzer mittels einer in sich arretierten Handwerkzeugmaschine hohe Drehmomente auf das Werkzeug aufgebracht. Es hat sich gezeigt, dass Bohrerdurchmesser über 17 mm vermehrt zu Schädigungen führen, konkret zum Bruch des Einsteckendes im Bereich der Verriegelungsnut und zu Zerstörungen innerhalb der Werkzeugaufnahme. Diese Brüche sind umso ärgerlicher, als das abgebrochene Ende im Inneren des Bohrhammers verbleibt und nur durch eine Demontage des Vorderteils des Bohrhammers aus der Werkzeugaufnahme entfernt werden kann. Selbst in den Fällen, in denen es beim Einsatz von Bohrern größerer Bohrerdurchmesser nicht zum Bruch kommt, zeigt sich eine plastische Deformation am Einsteckende, die zu einem unverhältnismäßig grossen Verschleiss der Werkzeugaufnahme führt, weswegen diese Werkzeuge oftmals nur schwer aus der Werkzeugaufnahme entfernt werden können.The practically standardized insertion ends and tool holders after the DE2551125A1 have a guide diameter of 10 mm, each exactly two uniform, diametrically opposed locking grooves and rotary driving grooves are distributed symmetrically circumferentially. At the respect to the locking grooves slightly longer rotary driving grooves adjoins the tool side to a tool-side end of the spigot extending guide surface, which does not contribute to torque transmission. These spigot ends were originally designed for a drill bit diameter of up to 17 mm and are thus to be classified as smaller, less powerful rotary hammers with a power of less than 650 W. The increasingly powerful hand tool machines, especially rotary hammers, however, now allow it to transfer high torques to a tool in certain operating modes. Meanwhile, an extension of the practical Field of application of these rotary hammers up to a drill diameter of 30 mm result. In addition, when removing a tool from the workpiece, especially when jammed in the hole tools, high torques are applied to the tool by the user by means of a self-locking hand tool. It has been shown that drill diameters greater than 17 mm increasingly lead to damage, specifically the breakage of the insertion end in the region of the locking groove and to destruction within the tool holder. These fractures are all the more annoying, as the broken end remains inside the hammer and can only be removed by disassembly of the front part of the hammer drill from the tool holder. Even in cases where it does not break when using drills larger drill diameter, a plastic deformation at the insertion, which leads to a disproportionate wear of the tool holder, which is why these tools are often difficult to remove from the tool holder.

Die ebenfalls praktisch standardisierten Einsteckenden und Werkzeugaufnahmen nach der DE3716915A1 weisen einen Führungsdurchmesser von 18 mm auf, wobei genau zwei gleichförmige, diametral gegenüberliegende Verriegelungsnuten vorhanden sind, zwischen diesen in einer Schnitthälfte genau eine und in der anderen Schnitthälfte genau zwei Drehmitnahmenuten symmetrisch angeordnet sind. Diese Einsteckenden sind für leistungsfähigere, grössere Bohrhämmer und der Übertragung höherer Drehmomente ausgelegt, wobei die in den obenstehenden Absätzen erläuterten Probleme bei noch höheren Leistungsklassen bzw. Drehmomenten naturgemäss ebenfalls auftreten. Werkzeuge mit einem Führungsdurchmesser von 18 mm, aber einem mit kleiner 14 mm wesentlich kleineren Bohrerdurchmesser weisen jedoch eine schlechte Schlagimpulsübertragung auf. Zudem wären derartige, unproportionierte Werkzeuge in der Herstellung unökonomisch.The also practically standardized Einsteckenden and tool holders after the DE3716915A1 have a guide diameter of 18 mm, with exactly two uniform, diametrically opposite locking grooves are present between them in a half of the section exactly one and in the other half of the section exactly two rotary driving grooves are arranged symmetrically. These spigots are designed for more powerful, larger rotary hammers and the transmission of higher torques, the problems explained in the paragraphs above naturally occur at even higher power classes or torques. However, tools with a guide diameter of 18 mm, but with a smaller 14 mm drill diameter significantly smaller, have a poor impact pulse transmission. Moreover, such disproportionate tools would be uneconomic in manufacture.

Die dabei auftretenden Belastungen setzen sich wie folgt zusammen: Zum einen erfolgt eine Belastung des Einsteckendes durch die Schlagenergie des Bohrhammers, zum anderen erfolgt eine, durch das an der Schneide auftretende Drehmoment bestimmte, von den Drehkeilen der Werkzeugaufnahme ausgehende Torsionsbelastung, die sich auf die Drehmitnahmenuten des Einsteckendes überträgt. Diese Drehmomentbelastung ist dann besonders hoch, wenn es z. B. zum Verkeilen der Schneide beim Armierungsbohren kommt. Als zusätzliche Belastung tritt im Fall des Verkeilens in Armierung, beispielsweise beim Versuch des Zurückziehens des Bohrhammers, zudem noch eine von dem Verriegelungskörper auf das Axialverriegelungsende der Verriegelungsnut einwirkende Belastung auf diesen gefährdeten, hinteren Querschnitt der Verriegelungsnut auf. Die langjährigen Erfahrungen haben nunmehr gezeigt, dass durch diese kombinierten, mehrachsigen Belastungen besonders der im Bereich des Axialverriegelungsendes angeordnete Querschnitt gefährdet ist. Die bruchmechanische Ursache dessen liegt vermutlich in diesem am Axialverriegelungsende lokal ausgeprägten, mehrachsigen Spannungszustand, der über die Querkontraktion eine lokale Versteifung bewirkt, welche einen bevorzugten Rissinitiator darstellt und somit die Dauerfestigkeit des wechselbeanspruchten Einsteckendes beschränkt.On the one hand there is a load of the spigot by the impact energy of the hammer drill, on the other hand takes place by the torque occurring at the cutting certain, starting from the rotary wedges of the tool holder torsional load on the Drehitnahmenuten of the insertion ends. This torque load is particularly high when it is z. B. comes to wedging the blade during Armierungsbohren. As an additional burden occurs in the case of wedging in reinforcement, for example, when attempting to retract the hammer drill, also on the end of the locking body acting on the Axialverriegelungsende the locking groove load on this vulnerable, rear cross-section of the locking groove. Many years of experience have now shown that these combined, multiaxial loads, in particular the cross section arranged in the region of the axial locking end is endangered. The fracture-mechanical cause of this is probably in this Axialverriegelungsende locally pronounced, multiaxial stress state, which causes a local stiffening on the transverse contraction, which is a preferred crack initiator and thus limits the fatigue strength of the loaded insertion end.

Nach der DE4338818 weist ein zur Aufnahme in eine Werkzeugaufnahme, welche ebenfalls für ein Einsteckende geringeren Führungsdurchmessers geeignet ist, ausgebildetes Einsteckende grösseren Führungsdurchmessers extra tiefe Drehmitnahmenuten und Verriegelungsnuten auf. Der in diesem Axialbereich extrem geschwächte Querschnitt weist wie oben ausgeführt eine schlechte Schlagimpulsübertragung und eine geringe Bruchfestigkeit auf.After DE4338818 has a for insertion into a tool holder, which is also suitable for a shank smaller guide diameter, trained insertion larger guide diameter extra deep rotary driving grooves and locking grooves. The extremely weakened cross-section in this axial region has, as stated above, a poor shock pulse transmission and a low breaking strength.

Die Aufgabe der Erfindung besteht in der Realisierung eines zur schädigungsarmen Übertragung hoher Drehmomente sowie optimaler Schlagimpulsübertragung ausgelegten Einsteckendes.The object of the invention is to realize a low-damage transmission of high torques and optimal impact pulse transmission designed Einsteckendes.

Die Aufgabe wird im Wesentlichen durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The object is essentially achieved by the features of claim 1. Advantageous developments emerge from the subclaims.

So weist ein Einsteckende eines zumindest teilweise längs einer Achse drehend und/oder schlagend angetriebenen Werkzeugs, welches sich längs der Achse innerhalb eines maximalen Führungsdurchmessers erstreckt sowie zumindest eine, an einem Axialverriegelungsende zum freien Stirnende hin axial geschlossene, Verriegelungsnut für Verriegelungsmittel einer Werkzeugaufnahme und Drehmitnahmenuten für Drehmitnahmemittel derselben Werkzeugaufnahme mit einer Nutenbreite mit zumindest einer Tangentialkraftkontaktfläche aufweist, zumindest zwei Drehmitnahmenuten auf, welche bei einer, zumindest dem Dreifachen des Führungsdurchmessers betragenden, Länge dem Axialverriegelungsende werkzeugseitig vorgelagert sowie zumindest über eine, zumindest dem 1.5-fachen des Führungsdurchmessers betragenden, Kontaktlänge breiter als ein Viertel des Führungsdurchmessers ausgebildet sind.Thus, an insertion end of an at least partially along an axis rotationally and / or hitting driven tool which extends along the axis within a maximum guide diameter and at least one, at an Axialverriegelungsende to the free end end axially closed, locking groove for locking means of a tool holder and rotary driving grooves for Rotary driving means of the same tool holder having a groove width with at least one Tangentialkraftkontaktfläche, at least two rotational drive grooves, which at one, at least three times the guide diameter amount upstream of the Axialverriegelungsende tool side and at least over a, at least 1.5 times the guide diameter amount, contact length wider than a quarter of the guide diameter are formed.

Durch die zumindest in einer wesentlichen Kontaktlänge dem Axialverriegelungsende werkzeugseitig vorgelagerten Drehmitnahmenuten wird zumindest der wesentliche Teil des Drehmoments ausschliesslich werkzeugseitig vom Axialverriegelungsende eingeprägt. Der bruchmechanisch kritische Axialbereich des mehrachsigen Spannungszustandes am Axialverriegelungsende ist somit notwendig geringeren Belastungen ausgesetzt, wodurch bei gegebener Dauerfestigkeitsgrenze ein höheres Drehmoment einprägbar ist. Insbesondere sind dadurch höhere Drehmomente bei geringerem Führungsdurchmesser schädigungsarm einprägbar, wodurch das Schlagimpulsverhalten bei kleinen Bohrerdurchmessern verbessert wird.Due to the at least a substantial contact length of the Axialverriegelungsende tool side upstream rotary drive grooves at least the major part of the torque is impressed exclusively on the tool side of Axialverriegelungsende. The fracture-mechanically critical axial region of the multiaxial stress state at the axial locking end is thus necessarily exposed to lower loads, whereby a higher torque can be impressed for a given fatigue limit. Especially As a result, higher torques with a smaller guide diameter can be impressed with little damage, thereby improving the impact pulse behavior with small drill diameters.

Vorteilhaft ist eine axiale Führungslänge zwischen einem werkzeugseitigen Führungsende mit dem Führungsdurchmesser bis zu einem werkzeugseitigen Nutende zumindest zweier Drehmitnahmenuten kleiner dem 1.5-fachen des Führungsdurchmessers, wodurch bis nahe an das werkzeugseitige Ende des Einsteckendes ein Drehmoment einprägbar ist.Advantageously, an axial guide length between a tool-side leading end with the guide diameter to a tool-side groove end of at least two rotary drive grooves smaller than 1.5 times the guide diameter, which is up close to the tool-side end of the insertion end torque can be embossed.

Vorteilhaft ist das Nutende von einem werkzeugseitigen Verriegelungsende zumindest um das 1.5-fache des Führungsdurchmessers axial werkzeugseitig versetzt, wodurch in diesem Axialbereich der Querschnitt nicht durch Verriegelungsnuten geschwächt ist, wodurch sich die Torsionssteifigkeit erhöht und höhere Drehmomente verschleissarm einprägbar sind.Advantageously, the groove end of a tool-side locking end is axially offset tool at least 1.5 times the guide diameter, whereby in this axial region of the cross-section is not weakened by locking grooves, which increases the torsional stiffness and higher torques are einprägbar verschleissarm.

Vorteilhaft verläuft zumindest über die Kontaktlänge die Tangentialkraftkontaktfläche sowohl parallel als auch senkrecht zur Achse, wodurch die Flächennormale der Tangentialkraftkontaktfläche exakt tangential orientiert ist und somit keine verschleissbegünstigenden Scherkräfte bei der Einprägung des Drehmoments induziert werden.Advantageously, at least over the contact length, the tangential force contact surface runs both parallel and perpendicular to the axis, as a result of which the surface normal of the tangential force contact surface is oriented exactly tangentially and thus no wear-promoting shearing forces are induced in the impressing of the torque.

Vorteilhaft beträgt zumindest über die Kontaktlänge die radiale Nutentiefe jeder Drehmitnahmenut zwischen dem 0.5 bis 1.0 fachen der Nutbreite, wodurch hohe Drehmomente ohne wesentliche Schwächung des Querschnitts bei hinreichender Biegesteifigkeit der in die Drehmitnahmenut eingreifenden Drehmitnahmestege der Werkzeugaufnahme einprägbar sind.Advantageously, at least over the contact length, the radial groove depth of each rotational drive groove between 0.5 to 1.0 times the groove width, whereby high torques without substantial weakening of the cross section with sufficient bending stiffness of engaging in the rotary driving rotary driving webs of the tool holder are einprägbar.

Vorteilhaft sind zumindest drei Drehmitnahmenuten vorhanden, die weiter vorteilhaft spiegelsymmetrisch angeordnet sind, wodurch ein höheres Drehmoment einprägbar ist.Advantageously, at least three rotary driving grooves are provided, which are further advantageously arranged mirror-symmetrically, whereby a higher torque can be embossed.

Vorteilhaft sind zwei, diametral versetzte Verriegelungsnuten vorhanden, wodurch das Einsteckende ergonomisch günstig in zwei um 180° versetzte Orientierungen in die Werkzeugaufnahme einführbar ist.Advantageously, there are two diametrically offset locking grooves, whereby the insertion end can be inserted ergonomically into the tool holder in two orientations offset by 180 °.

Vorteilhaft gehen die Verriegelungsnuten werkzeugseitig in die Drehmitnahmenuten über, wodurch der Querschnitt weniger geschwächt wird.Advantageously, the locking grooves go over the tool side in the rotary driving grooves, whereby the cross section is less weakened.

Alternativ vorteilhaft sind die Drehmitnahmenuten von den Verriegelungsnuten werkzeugseitig axial beabstandet, wodurch die Funktionsbereiche voneinander getrennt und somit technologisch einfach herstellbar sind.Alternatively advantageously, the rotary driving grooves are axially spaced from the locking grooves on the tool side, as a result of which the functional regions are separated from one another and thus can be produced in a technologically simple manner.

Vorteilhaft sind die Drehmitnahmenuten von den Verriegelungsnuten, weiter vorteilhaft symmetrisch, umfänglich versetzt, wodurch für die Drehmitnahmemittel und die Verriegelungsmittel in der zugeordneten Werkzeugaufnahme mehr Freiraum besteht.Advantageously, the rotary driving grooves of the locking grooves, further advantageously symmetrical, circumferentially offset, whereby there is more freedom for the rotary driving means and the locking means in the associated tool holder.

Vorteilhaft sind die Drehmitnahmenuten maschinenseitig offen, wodurch die Drehmitnahmemittel vom Stirnende des Einsteckendes in die Drehmitnahmenuten einführbar sind.Advantageously, the rotary driving grooves are open on the machine side, whereby the rotary driving means can be inserted from the front end of the insertion end into the rotary driving grooves.

Nach Fig. 1a, Fig. 1b weist ein Einsteckende 1 eines längs einer Achse A drehend und schlagend angetriebenen Werkzeugs 2, welches sich längs der Achse A mit einem maximalen Führungsdurchmesser D erstreckt, jeweils genau zwei gleiche, diametral angeordnete, an einem Axialverriegelungsende 3 zum freien Stirnende 4 hin axial geschlossene, Verriegelungsnuten 5 und Drehmitnahmenuten 6 mit einer sowohl parallel als auch senkrecht zur Achse A verlaufenden Tangentialkraftkontaktfläche 7 auf. Zwischen einem werkzeugseitigen Führungsende 12 mit dem Führungsdurchmesser D bis zu einem werkzeugseitigen Nutende 13 beider Drehmitnahmenuten 6 ist eine axiale Führungslänge F der Hälfte des Führungsdurchmessers D ausgebildet. Das Nutende 13 ist von einem werkzeugseitigen Verriegelungsende 14 um mehr als das Doppelte des Führungsdurchmessers D axial werkzeugseitig versetzt. Über eine Kontaktlänge K vom Doppelten des Führungsdurchmessers D hin sind beide Drehmitnahmenuten 6 mit einer konstanten Nutenbreite B von einem Drittel des Führungsdurchmessers D ausgebildet und bis zu einer Länge L, welche länger als das Dreifache des Führungsdurchmessers D ist, dem Axialverriegelungsende 3 werkzeugseitig vorgelagert. Die Verriegelungsnuten 5 gehen jeweils werkzeugseitig in die Drehmitnahmenuten 6 über, wobei eine radiale Nutentiefe T beider Drehmitnahmenuten 6 über die gesamte Kontaktlänge K die Hälfte der Nutbreite B beträgt.To Fig. 1a, Fig. 1b has a spigot 1 of a longitudinal axis A rotationally and strikingly driven tool 2, which extends along the axis A with a maximum guide diameter D, respectively exactly two same, diametrically arranged, at an Axialverriegelungsende 3 to the free end 4 out axially closed, locking grooves 5 and rotary driving grooves 6 with a both parallel and perpendicular to the axis A extending tangential force contact surface 7. Between a tool-side guide end 12 with the guide diameter D to a tool-side groove end 13 of both rotary driving grooves 6, an axial guide length F of half of the guide diameter D is formed. The groove end 13 is offset by a tool-side locking end 14 by more than twice the guide diameter D axially tool side. Over a contact length K of twice the guide diameter D out both Drehitnahmenuten 6 are formed with a constant groove width B of one third of the guide diameter D and up to a length L which is more than three times the guide diameter D, the Axialverriegelungsende 3 upstream tool side. The locking grooves 5 each go on tool side in the rotary driving grooves 6, wherein a radial groove depth T of both rotary driving grooves 6 over the entire contact length K is half the groove width B.

Nach Fig. 2 ist die Drehmitnahmenut 6 mit der, ein Drittel des Führungsdurchmessers D betragenden, Nutbreite B von den beiden, diametral gegenüberliegenden Verriegelungsnuten 5 werkzeugseitig axial beabstandet sowie um 90° umfänglich versetzt, wobei die Führungslänge F die Hälfte, die Kontaktlänge K das Doppelte und die Länge L das 3.5-fache des Führungsdurchmessers D ist.To Fig. 2 is the Drehitnahmenut 6 with, amounting to one third of the guide diameter D, groove width B of the two diametrically opposed locking grooves 5 tool axially spaced and circumferentially offset by 90 °, the guide length F half, the contact length K twice and the length L which is 3.5 times the guide diameter D.

Nach den Fig. 3a, 3b ist ein spiegelsymmetrisches Einsteckende 1 in eine zugeordnete, angedeutete Werkzeugaufnahme 8 mit Drehmitnahmemitteln in Form von drei radial nach innen einkragenden, werkzeugseitig vorgelagerten Drehmitnahmestegen 9 und einem radial versetzbaren Verriegelungsmittel in Form einer Verriegelungskugel 10 eingeführt. Dazu sind die Drehmitnahmenuten 6 mit einer, breiter einem Fünftel des Führungsdurchmessers D betragenden, konstanten Nutenbreite B maschinenseitig bis zum freien Stirnende 4 hin offen. Die drei spiegelsymmetrisch angeordneten Drehmitnahmenuten 6 sind von den beiden diametral gegenüberliegenden Verriegelungsnuten 5 symmetrisch umfänglich versetzt. Die Führungslänge F ist das Einfache, die Kontaktlänge K das Vierfache und die Länge L das 3.5-fache des Führungsdurchmessers D, wobei das Nutende 13 von dem werkzeugseitigen Verriegelungsende 14 um das Doppelte des Führungsdurchmessers D axial werkzeugseitig versetzt ist.After the Fig. 3a, 3b is a mirror-symmetrical spigot 1 in an associated, indicated tool holder 8 with rotary driving means in the form of three radially inwardly projecting, tool-side upstream rotary driving webs 9 and a radially displaceable locking means in the form of a locking ball 10 introduced. For this purpose, the rotary driving grooves 6 are open with a constant groove width B amounting to one fifth of the guide diameter D on the machine side as far as the free front end 4. The three mirror-symmetrically arranged rotary driving grooves 6 are symmetrically circumferentially offset from the two diametrically opposed locking grooves 5. The guide length F is the simple, the contact length K four times and the length L 3.5 times the guide diameter D, wherein the groove end 13 is offset from the tool-side locking end 14 by twice the guide diameter D axially tool side.
